Hi! I'm having an issue notarizing my app. I've developed my app in python, packaged it with py2app and then codesigned it using command-line: codesign --deep --sign "Developer ID Application: Name (ID)" MyApp.app and verified it using: codesign --verify --verbose MyApp.app with no problem. I then continued to notarize it with notarytool: xcrun notarytool submit MyApp.zip --keychain-profile "MyProfile" --wait and everything went smoothly, however, the process ended as invalid. This is a recurring issue (used altool beforehand) where I get errors that prevent the notarization due to signature issues, some of them: "The signature of the binary is invalid." "The executable does not have the hardened runtime enabled." "The binary is not signed with a valid Developer ID certificate." "The signature does not include a secure timestamp." And so on. The issue is that this is occurring to the contents of the app and the python libraries and other dependencies it uses, not MyApp.app itself. I've read online in many places and couldn't find what am I missing, I've followed the code-signing and notarization instructions to no prevail. I hope someone here can help me solve this problem or figure out what am I missing. Many thanks :)
